(Taonidium) suhmi, but these have little in common with T . suhmi
Hoyle, 1885 and will be dealt with under Baliteuthis armuta.
Various specimens have been called by this name but a reassessment of each is beyond the scope of this work and will be
necessary before a discussion of distribution can be attempted.
3. Taonidium incertum Pfeffer, 1912
a mantle length of 0.6 cm.
4. Taonidium pfefferi Russell, 1909
This has been recorded from various localities in the eastern North
Atlantic (Russell, 1909; Pfeffer, 1912; Massy, 1913; Degner, 1925;
Bouxin and Legendre, 1936) and the Mediterranean (Degner, 1925).
It has been caught in open nets fished to a depth of 550 m but Russell
(1909) thought that it is probably a surface form and Degner (1926)
found that 18 out of 26 were caught with less than 300 m of wire out
(i.e. at a depth of less than 150 m). The largest specimen has an
estimated mantle length of 3-7 cm (Massy, 1913). Two specimens
were recovered from Bermo alalunga stomachs (Bouxin and Legendre,
1936).
M. Teuthowenia
Known only from the type this was taken at 47' 30" 16'W, and has
The specimens referred to this genus have similar larval characters
to Taonidium and also have distinct but short eye stalks (Fig. 49).
1. Teuthowenia anturctica Chun, 19 10
Owenda n. sp. Chun, 1903c
This was considered a synonym of Desmoteuthis megabps (Prosch,
1849) by Muus (1956) on rather inadequate evidence (Dell, 1959a). It
has been recorded from 55'57'5 16'14'E (Chun, 1910a), from off New
Zealand (Massy, 1916c) and from the Southern Ocean at 64'21'5
116'02'E and 65'10'5 109'32'E (Dell, 1959a). It has been taken at the
surface (Massy, 1916c) and in an open vertical net fished to 2 000 m
(Chun, 1910a). The largest specimen has a mantle length of 1-3 cm
(Chun, 1910a).
2. Teuthowenia corona Berry, 1920
The single specimen known in this species has arms approaching
those of Megalocranchia in length but has other features of Teuthowenia.
It was caught at 32"27'N 68'22'W at 100-0 m and has a mantle length
of 2.7 cm.
